Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-editing-services/-/merge_requests/204>

smart-mixer: Move the videoconvert to after the mixer

So that it tries to negotiate with alpha and the alpha channel is
dropped as late as possible in the pipeline.

The compositor is able to do video conversion internally in any case
so having a videoconvert before it is useless.

smart-mixer: Use the new 'samples-selected' signal to handle queuing in aggregator pads

Since aggregator introduced queueing in its sinkpads the way we set
properties on the pads is incorrect as it doesn't take it into account.
This fixes the issue by using the newly introduced `samples-selected`
signal in aggregator to set the properties right before the compositing
is done.

Also require the compositor we use to be an aggregator.

Smart rendering has been broken since, mostly forever, but some code
was there pretending it was supported... let's try to stop pretending.

We now keep track of the smart rendering state in the timeline, track
and sources to be able to:

 * tell decodebin to stop plugging more (decoding elements) as soon as

overwrite a users own setting of the caps for video and audio caps.

We need to ensure that clips duration is set after time effects are

Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-editing-services/-/merge_requests/177>

docs: add some notes on Time in GES

These notes cover time coordinates in GES, time effects, time
translations.

It also goes into why keyframes will not work with non-linear time
effects.

Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-editing-services/-/merge_requests/177>

uri-clip: don't assume duration needs to stay the same

ges_uri_clip_asset_get_duration does not tell us what the duration in
the timeline needs to be. Especially when we have time effects, or
effects with finite max-durations. So we should no longer expect the
duration to stay the same when replacing assets. Instead, we just check
that the new max-duration would be compatible with the current in-point
(which was not checked before), and the clip would not be totally
overlapped if its duration-limit changes.

This is based on the assumption that each source is replaced one-to-one
in its track. If a source is replaced with nothing in the same track,
this check may be a little too strong (but still mostly weaker than
before). However, problems could occur if track selection does
something unexpected, such as placing the new source in a track not
previously occupied.

Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-editing-services/-/merge_requests/177>

track-element: use out-point for updating control bindings

The out-point, which is an internal time, is used instead of the
duration for determining the control binding value at the end of the
element.

Also, allow the user to switch off the auto-clamping of control sources
if they are not desired. And allow them to clamp specific control sources
individually.

Also, fix a lot of memory leaks related to control sources. In
particular, releasing the extra ref gained by source in
g_object_get (binding, "control-source", &source, NULL);

clip: test for layer in group

Make sure the layer exists before we try to remove the grouped clips

Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-editing-services/-/merge_requests/177>

timeline-tree: make sure the layer priority refers to an existing layer

If a layer priority sits between the priorities of two layers in the
timeline, i.e. it references a gap in the timeline's layers, then
ges_timeline_append_layer will never fill this gap and create the
desired layer, so the edit in timeline-tree would loop forever. So a
check was added to avoid this.

This would be a usage error, but a user can reasonably end up with a gap
in their layers if they remove a layer from the timeline.

Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-editing-services/-/merge_requests/177>

clip: add method for adding top effects

Unlike ges_container_add, this lets you set the index and will check
that track selection did not fail. This is useful for time effects whose
addition would create an unsupported timeline configuration.

Also can use the clip add error in ges_timeline_add_clip to let the user
know when adding a clip to a layer that its in-point is set larger than
the max-duration of its core children.

Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-editing-services/-/merge_requests/177>

timeline-tree: take time effects into account when trimming

When trimming the start of a clip, we want to set the in-point of its
children such that whatever data was at the timeline time T still
remains at the timeline time T after the trim, where
  T = MAX (prev_start, new_start)

Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-editing-services/-/merge_requests/177>

clip: use time translation for split

The new in-point should be the media position corresponding to the media
position. media_duration_factor is no longer needed.

effect: Add support for time effects

Allow the user to register a child property of a base effect as a time
property. This can be used by GES to correctly calculate the
duration-limit of a clip when it has time effects on it. The existing
ges_effect_class_register_rate_property is now used to automatically
register such time effects for rate effects.

Added more errors to GES_ERROR for when edits fail (other than

a GstMessage somewhere which is freed by, any thread.

In this specific case we can assume that GES user will already have

It is the right ordering and in Pitivi we set the project size

clip: enforce duration-limit

Prevent setting of properties or that of children, if the clip would not
be able to set the corresponding duration if the duration-limit would
drop below the currently set duration.

clip: make sure core child is active for non-core in same track

Each active non-core child must have a corresponding active core child
in the same track. Therefore, if we de-activate a core child, we also
need to de-activate all the non-core children in the same track.
Similarly, if we activate a non-core child, we need to activate the
corresponding core child as well.
